OpenStudy (saifoo.khan):

\[\Large \frac{\frac14}{\frac13}\]\[\Large \frac14 \div \frac13\]\[\Large \frac14 \times \frac31\] \[\Large \frac34\]

OpenStudy (anonymous):

when u hv to divide a fraction by another fraction, you change division to multiplication and take the multiplicative inverse of the second fraction as I hv done...

OpenStudy (saifoo.khan):

Can u please rewrite the question only? and is that question compelete?

OpenStudy (saifoo.khan):

Complete*

OpenStudy (saifoo.khan):

OpenStudy (saifoo.khan):

i made the question harder. :( sowwie.

OpenStudy (saifoo.khan):

Sure, okay.. so.. let's do the 4rd part. \[Tasbasco sause = \frac14 \times \frac56\] \[Red onions = \frac13 \times \frac56\]and so on.

OpenStudy (anonymous):

how was question 1, 2, 3 ,4

OpenStudy (saifoo.khan):

Sorry again, i showed working for 3rd part. typos! >_<

OpenStudy (saifoo.khan):

For forth question, sause = 1/4 * 1/4 onions = 1/3 * 1/4 and so on

OpenStudy (anonymous):

do we reduce

OpenStudy (anonymous):

* multiply

OpenStudy (saifoo.khan):

\[\frac14 \times 14 = \frac{1}{16}\] \[\frac13 \times \frac 14 = \frac{1}{12}\]

OpenStudy (saifoo.khan):

Yes ma'am.

OpenStudy (anonymous):

so all of them are just multiplying and reducing

OpenStudy (saifoo.khan):

YES!
